Moisture on Plotter Users should use the plotter in an environment between 5% and 95% relative humidity. To recover from moisture condensation, turn the plotter off, and, using the main roller as a reference, wait until the plotter is completely dry before using it again. (Other environmental specifications ' chapter 2.) Level of Plotter Usage To achieve good performance and long lifetime of the HP DesignJet 230/250C and HP DesignJet 330/350C plotters, users should limit use to the following recommendations (duty cycle): Average number of plots per day Maximum number of plots per day 10 E/A0 CAD plots 20 E/A0 CAD plots The service configuration plot gives an indication of how much the plotter has been used: number of plots, number of cartridges, number of times the plotter has been turned on. (Details ' page 8Ć49/8Ć50.) Friction on Slider Rod The carriage bushings are made of a porous composite material. Oil stays inside them by means of capillary action. Never place the bushings on an absorbant material. To prevent friction of the bushings on the slider rod, remove dirt from the slider rod and chassis beam. Apply oil (Anderol 4068, HP part number: 6040Ć0858) to the slider rod ( 3 drops) and to the bushings if they are running dry. Noisy Carriage Wheel To prevent noisy movement of the carriage, remove aluminum or dust particles from the wheel at the back of the carriage, and from the slider path along which the wheel moves. 4Ć2 Preventive Maintenance C4699Ć90000
